A judge yesterday sentenced a man and woman to 25 years to life in prison for killing a good Samaritan who gave them a lift on the Belt Parkway after their car broke down.

“That conduct is indescribable. That conduct is intolerable. That conduct is unacceptable,” Judge Albert Tomei said in Brooklyn Supreme Court.

His sentence – the max for second-degree murder – came after victim Rupinder Singh’s mother pleaded with the judge to throw the book at Darshen Kingsberry and Jack Govan, who were convicted at trial last month.

Assistant DA Mitch Benson told the judge that Kingsberry’s toddler daughter, who witnessed the slaying, later told authorities that her uncle “popped the man,” then clapped her hands to make the sound of a gunshot, recited her ABCs and 123s, and then clapped her hands again.

“This is what she subjected her child to,” Benson said. “The court knows what she subjected someone else’s child to.”
